709079S9PF

Memory IC Overview

The Renesas Electronics Corporation 709079S9PF is a high-speed 256Kb (32K x 8) synchronous dual-port static RAM. It features true dual-ported memory cells allowing simultaneous access to the same location from both ports. The device operates on a single 5V power supply with TTL-compatible inputs and outputs. It supports flow-through or pipelined output modes selectable via the FT/PIPE pin. The component includes address counter enable and reset features, automatic power-down capabilities controlled by chip enables, and depth expansion support without additional logic.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent access to shared memory locations
• Configurable flow-through or pipelined output modes for optimized data throughput
• Integrated address counter with enable and reset functions for sequential burst operations
• Automatic low-power standby mode activated through specific chip enable configurations

Memory IC Applications

• High-speed unidirectional or bidirectional data flow in burst applications
• Depth expansion configurations requiring multiple chip enables
• Systems utilizing self-timed write cycles with fast cycle times

Memory IC Procurement Notes

Verify the exact speed grade suffix against current manufacturer documentation, as ordering codes may have evolved following corporate acquisitions. Confirm package availability and moisture sensitivity levels prior to design finalization. Ensure compliance with RoHS directives if required for the target application environment.

Memory IC Selection Notes

Select this component when simultaneous read/write access to identical addresses is required. Choose between flow-through and pipelined modes based on latency requirements. Verify that the system clock frequency aligns with the specified setup and hold times for reliable operation.

Memory IC Part Context

This part belongs to the IDT709089/79 family of synchronous dual-port SRAMs. It shares architectural similarities with other members like the 709079S12PF but offers faster access speeds. The device utilizes CMOS high-performance technology and is available in a 100-pin TQFP package suitable for surface mount applications.
